Creating an ECS for the SAP HANA and SAP Business One Node

Scenarios

Based on the deployment scheme, create an ECS to deploy the SAP Business One software and SAP HANA database.

For details about the ECS specifications, see sections Deployment Modes and Node Planning.

Procedure

Log in to the management console, click and choose Computing > Elastic Cloud Server.
On the right side of the page, click Buy ECS.

Set the parameters as prompted.

**Table 1** Basic configuration
Parameter	Description
Billing Mode	Select a billing mode based on the site requirements. The recommended billing mode is Yearly/Monthly.
AZ	Specifies the AZ where the ECS is located.
CPU Architecture	The value can be x86 or Kunpeng. x86: The X86-based CPU architecture uses Complex Instruction Set Computing (CISC). Each instruction can be used to execute low-level hardware operations, and the length of each instruction is different. Therefore, the number of instructions is large and they are complex. Therefore, executing such an instruction is complex and time-consuming. Kunpeng: The Kunpeng-based CPU architecture uses Reduced Instruction Set Computing (RISC). RISC is a microprocessor that executes fewer types of computer instructions but at a higher speed than CISC. RISC simplifies the computer architecture and improves the running speed. Compared with the x86-based CPU architecture, the Kunpeng-based CPU architecture has a more balanced performance and power consumption ratio. Kunpeng features high density, low power consumption, high cost-effectiveness.
Specifications	Click Large-memory, General computing-plus, or Memory-optimized. Select a specification based on Node Planning or as required.
Image	Click Marketplace image. In the displayed Select Marketplace Image dialog box, enter SAP in the search box and select the target image.
System Disk	Plan the system disk and data disk by referring to section Node Planning.

Click Next: Configure Network.

Configure the network information of the SAP HANA and SAP Business One node as prompted.

**Table 2** Network configuration
Parameter	Description
Network	Choose the VPC and subnet in specified in Applying for a Subnet and Configuring a Security Group.
Extension NIC	Create an NIC by referring to section Network Planning.
Security Group	Use the security group in section Applying for a Subnet and Configuring a Security Group.
EIP	Select Not required. The SAP HANA and SAP Business One ECS on the private subnet can be accessed through the NAT server.

Click Next: Configure Advanced Settings.

Configure parameters in advanced settings of the ECS as prompted.

**Table 3** Advanced configuration
Parameter	Description
ECS Name	When you create ECSs in batches, the number in the ECS Name is generated automatically in ascending order based on the Quality value that you filled in. For example, if you fill SAP-Dev in ECS Name, the first ECS is SAP-Dev-0001, and the second ECS is SAP-Dev-0002.
Login Mode	Select Key pair.
Key Pair	An SSH key certificate will be used for authenticating users who attempt to log in to SAP HANA and SAP Business One ECS. Ensure that the ECSs where SAP HANA and SAP Business One as well as the NAT server are to be deployed use the same key. Otherwise, SAP HANA and SAP Business One installation will fail. If you choose an existing SSH key certificate from the drop-down list, make sure that you have saved the certificate locally. Otherwise, you may fail to log in to the ECS. Click View Key Pair. On the Key Pair page that is displayed, click Create Key Pair, specify the key pair name, and click OK. In the Information dialog box that is displayed, click OK. Then, you can query and save the private key as prompted.
Cloud Backup and Recovery	Cloud Backup and Recovery (CBR) provides backup protection for EVS disks and ECSs, and uses backups to restore the EVS disks and ECSs. After you set Cloud Backup and Recovery, the system binds the target ECS to the cloud backup vault and associates the ECS with the selected backup policy to periodically back up the ECS. You can select one of the following three options for EIP as required: Auto assign Set the name of the cloud backup vault, which is a character string consisting of 1 to 64 characters, including letters, digits, underscores (_), and hyphens (-). For example, vault-f61e. The default naming rule is vault_xxxx. Enter the vault capacity, which is required for backing up the ECS. The vault capacity cannot be smaller than that of the ECS to be backed up. Its value ranges from the total capacity of the ECS to 10,485,760 in the unit of GB. Select a backup policy from the drop-down list, or log in to the CBR console and configure a desired one. Use existing Select an existing cloud backup vault from the drop-down list. Select a backup policy from the drop-down list, or log in to the CBR console and configure a desired one. Not required: This function is not required. If you require this function after purchasing the ECS, log in to the CBR console and bind the desired cloud backup vault to your ECS.
ECS Group (Optional)	This parameter is displayed only after you click Configure now behind Advanced Options. Specify an SAP HANA and SAP Business One ECS group. When you create ECSs, the system will allocate the ECSs in the same server group to different physical servers to ensure the running reliability of these ECSs. Determine the policy of an SAP HANA and SAP Business One ECS group based on the deployment mode: Single-node scenarios: You do not need to specify an ECS Group. Cluster scenarios: All SAP HANA and SAP Business One ECSs must belong to the same ECS Group. NOTE: Perform the following operations to create an ECS group: Click Create ECS Group. On the page that is displayed, click Create ECS Group, specify the ECS group name, and click OK.
Advanced Options	Select Configure now.
Agency	After the agency is specified, the delegated domain can obtain the credentials from the agency to temporarily access the public cloud. You need to choose the DataproviderAccess agency for the SAP HANA and SAP Business One ECS to interconnect with Data Provider. Log in to the public cloud management console as a tenant administrator, click Service List and choose Management & Deployment > Identity and Access Management > Agencies. Then, click Create Agency on the right side of the page. Set the parameters as follows: Agency Name: DataProviderAccess Agency Type: Cloud service Cloud Service: Elastic Cloud Server (ECS) and Bare Metal Server (BMS) Validity Period: Retain the default setting. Permissions: Locate the Region and Project Name in which the target ECSs locate, click Attach Policy in the Operation column, and choose Base > Tenant Guest to configure the permissions for the ECS.

Click Next: Confirm.

Confirm the configuration information of the SAP HANA and SAP Business One node as prompted.

**Table 4** Parameters of the SAP HANA and SAP Business One node
Parameter	Description
Enterprise Project	Select the name of a created enterprise project, for example, SAP.
Required Duration	Set the duration based on your requirements.
Quantity	Set this parameter as required.
Agreement	Select I have read and agree to Huawei Image Disclaimer.

Click Next and complete the payment as prompted.
On the displayed Elastic Cloud Server page, check the status of the created task in Task Status on the right of the page.
Change the password of user root for logging in to all HANA ECSs.
Securely keep the root password. In addition, ensure that all HANA ECSs use the same root password.
1. Use the key to log in to the SAP HANA ECSs.
2. Run the following command to change the password of user root:
  passwd
  
  Enter the new password as prompted and confirm it.
